Antonio Sanchez ad82d20cf6 Fix checking of version number for mingw.
MinGW spits out version strings like: `x86_64-w64-mingw32-g++ (GCC)
10-win32 20210110`, which causes the version extraction to fail.
Added support for this with tests.

Also added `make_unsigned` for `long long`, since mingw seems to
use that for `uint64_t`.

Related to #2268.  CMake and build passes for me after this.
